openclaw-multi-session-plugins

OpenClaw plugin for logical multi-session isolation and scoped XWorkmate artifact manifests.

Why

XWorkmate talks to OpenClaw through xworkmate-bridge using the existing /gateway/openclaw task contract. The bridge sends chat.send, waits for agent.wait, then asks this plugin for a session/run-scoped artifact manifest. The APP can then sync generated files into its local thread workspace without changing the UI or adding provider-specific routes.

This plugin is not a scheduler. OpenClaw core owns sub-agents, multi-agent routing, queues, cron, and cross-session execution. This package only adapts those existing OpenClaw multi-task/session identities into isolated artifact directories and signed artifact reads.

It registers four Gateway methods:

xworkmate.artifacts.prepare
xworkmate.artifacts.export
xworkmate.artifacts.list
xworkmate.artifacts.read

prepare creates a per-task artifact scope under tasks/ in the resolved OpenClaw workspace. export and read then return safe, relative artifact entries that XWorkmate Bridge can normalize into the APP artifacts[] contract.

Install

Install from the npm package through OpenClaw:

openclaw plugins install openclaw-multi-session-plugins
openclaw plugins enable openclaw-multi-session-plugins

Or install from a Git checkout for development:

git clone https://github.com/x-evor/openclaw-multi-session-plugins.git
openclaw plugins install --link ./openclaw-multi-session-plugins
openclaw plugins enable openclaw-multi-session-plugins

Equivalent config shape for a linked checkout:

{
  "plugins": {
    "load": {
      "paths": [
        "/path/to/openclaw-multi-session-plugins"
      ]
    },
    "entries": {
      "openclaw-multi-session-plugins": {
        "enabled": true
      }
    }
  }
}

Contract

Prepare request params are supplied by the OpenClaw host, bridge, or APP runtime. The plugin treats sessionKey, runId, and workspaceDir as the trusted mapping into OpenClaw's built-in multi-session model; it does not parse paths from chat text and does not invent fallback session/run identities.

{
  "sessionKey": "thread-main",
  "runId": "turn-1",
  "workspaceDir": "/home/user/.openclaw/workspace"
}

Prepare response payload:

{
  "runId": "turn-1",
  "sessionKey": "thread-main",
  "remoteWorkingDirectory": "/home/user/.openclaw/workspace",
  "remoteWorkspaceRefKind": "remotePath",
  "artifactScope": "tasks/thread-main-.../turn-1-...",
  "scopeKind": "task",
  "artifactDirectory": "/home/user/.openclaw/workspace/tasks/thread-main-.../turn-1-...",
  "relativeArtifactDirectory": "tasks/thread-main-.../turn-1-...",
  "warnings": []
}

Export request params:

{
  "sessionKey": "thread-main",
  "runId": "turn-1",
  "artifactScope": "tasks/thread-main-.../turn-1-...",
  "sinceUnixMs": 1770000000000,
  "latestIfEmpty": true,
  "maxFiles": 64,
  "maxInlineBytes": 10485760
}

Export response payload:

{
  "runId": "turn-1",
  "sessionKey": "thread-main",
  "remoteWorkingDirectory": "/home/user/.openclaw/workspace",
  "remoteWorkspaceRefKind": "remotePath",
  "artifactScope": "tasks/thread-main-.../turn-1-...",
  "scopeKind": "task",
  "artifacts": [
    {
      "relativePath": "reports/final.md",
      "label": "final.md",
      "contentType": "text/markdown",
      "sizeBytes": 1234,
      "sha256": "...",
      "artifactRef": "...",
      "artifactScope": "tasks/thread-main-.../turn-1-...",
      "scopeKind": "task"
    }
  ],
  "warnings": []
}

Files at or below maxInlineBytes also include encoding: "base64" and content. When scoped export finds no task files and latestIfEmpty is true, the plugin scans the workspace root for the latest real files and returns them with scopeKind: "workspace-latest". This is a controlled recovery path for existing files already present in /home/ubuntu/.openclaw/workspace; it still skips plugin metadata and runtime directories, including the top-level tasks/ directory so other runs are not exported as workspace fallback files.

Each exported artifact includes artifactRef, a plugin-signed reference over the artifact scope, path, size, and SHA-256 digest. read accepts artifactScope + relativePath for the current sessionKey/runId task scope. Signed task artifactRef values are accepted for the current session, including same-session historical task fallback results returned by the plugin. Workspace fallback files must be read with artifactRef; there is no unscoped arbitrary workspace read API.

View And Download

After installation, enable the optional agent tool if you want OpenClaw chat to show a quick artifact table:

{
  "agents": {
    "list": [
      {
        "id": "main",
        "tools": {
          "allow": ["openclaw_multi_session_artifacts"]
        }
      }
    ]
  }
}

Then ask OpenClaw to list artifacts in the current workspace. The tool returns a Markdown table with the workspace path, relative file paths, content types, file sizes, and hash prefixes. Files are still stored in the OpenClaw workspace, so local users can open or download them directly from that workspace path.

Gateway clients can use:

• xworkmate.artifacts.prepare before chat.send to allocate a task artifact directory.
• xworkmate.artifacts.list for a metadata-only manifest and Markdown table.
• xworkmate.artifacts.read with artifactScope and relativePath for one task file.
• xworkmate.artifacts.read with artifactRef for a plugin-returned task or workspace-latest file.
• xworkmate.artifacts.export with artifactScope after agent.wait for the XWorkmate APP sync path.

Large files are metadata-only in the export payload, but XWorkmate Bridge can generate its own signed download URL and call xworkmate.artifacts.read as the only remote file access path.

Limits

• Only files inside the resolved OpenClaw workspace are exported.
• .git, .openclaw, .xworkmate, .pi, build outputs, and dependency folders are skipped when scanning the workspace root.
• Top-level tasks/ is skipped during workspace fallback scanning.
• Symlinks are skipped to avoid workspace escape.
• Files larger than maxInlineBytes are listed with metadata and a warning, but are not inlined.
• artifactScope must be tasks/<safe-session-key>/<safe-run-id>.
• Direct artifactScope + relativePath reads and scoped exports must match the supplied sessionKey/runId.
• artifactScope, artifactRef, and relativePath must stay inside the workspace; absolute paths, .., empty path segments, and symlink escapes are rejected.
